## Discrepancy

THE PILOT AND MEDICAL CREW SMELLED FUEL IN THE CABIN SHORTLY AFTER TAKEOFF.  THE ODOR APPEARED TO BE MORE SIGNIFICANT IN THE AFT CABIN AREA.  THE PILOT IMMEDIATELY DECIDED TO LAND IN A CLEAR LANDING AREA.  THE MECHANIC WAS CALLED TO THE LOCATION WHERE HE INSPECTED THE AIRCRAFT AND FOUND APPROXIMATELY 2-3 OUNCES OF FUEL COLLECTED IN THE AFT BELLY PANEL.  IT WAS OBSERVED THAT THE FUEL FILTER SUMP DRAIN CLUSTER WAS NOT FITTED IN THE OVERFLOW SCUPPER WHICH ALLOWED THE FUEL TO DRAIN INTO THE BELLY PANEL.  THERE WAS NO INDICATION OF FUEL LEAKAGE OBSERVED.  THE SUMP DRAIN LINE WAS EXTENDED AND THE ACFT WAS RETURNED TO SERVICE.
